I still don't understand about the cropping or stabilization, however I guess I just see things differently.
On a similar topic which might be better to talk about, I don't understand how quality will be impacted in your plan.
For quality, what is the proper workflow for a project like this?
scan in at least 2x resolution of desired output resolution -> color correct -> stabilize -> descratch/denoise -> resize/crop?
Or does color correction come last as it seems would be in your plan?
